<p><P>PROBLEM TO BE SOLVED: To provide a color luminescent sheet capable of obtaining a precise image by a prescribed radiation quantity, capable of improving remarkably detection sensitivity or image information, and capable of obtaining a lot of information surely and effectively by a reduced photographing frequency, and to provide color Roentgen device (color Roentgen image forming device) using the sheet. <P>SOLUTION: In this color luminescent sheet 4 having a phosphor layer 9 containing a phosphor for emitting light by a radiation, and irradiated with the radiation transmitted through a specimen to emit luminescent light, the phosphor layer 9 contains the phosphor, and a fluorescent coloring matter having an emission spectrum including a main emission peak wavelength of the phosphor. A content of the fluorescent coloring matter is preferably within a range of 0.01-5.0 mass% with respect to the phosphor, in the phosphor layer 9. <P>COPYRIGHT: (C)2004,JPO</p> |
